Used SS's upgrade to 7.1, page width on some pages seems broken, unable to change.

Just did the Squarespace auto-upgrade from 7.0 to 7.1 - There are some normal quirky things I need to upgrade. However, one major issue I can't seem to figure out - 2 of my pages - the page width seems "stuck" at an odd width - not even what the site was before. These pages were full width before, however, I can't change it. Even if I try to edit the section, the section edit pop-up goes away... not sure how to fix this? Can see at this link:

Even if I add a new section, it does the same thing. The entire page feels like its set to 70% width (the site width in style is set to the default)

Any help is appreciated! We have active registration happening right now.

Well...sometimes typing out your problem, gives you a clue. 🙂 I had checked custom CSS and code injection to make sure no new code appeared from the upgrade, but as I typed "page" up top a couple of times, I realized I should check the individual page custom code area. Sure enough, when doing the upgrade, this code was added to the Page settings >advanced section. I 100% didn't have this code there prior, as the pages were full width in 7.0

Adding this info here in case someone else comes across this when they use the built-in upgrade feature.
